Things like this are just a total blessing to people who need them and its awesome to see affordable technology like this taking place for people who can't even take part in the one of the most important functions of life. A lot of people are talking about if there is a big enough market/etc, we should probably assume the creator only wants to cover his cost since this invention was probably created by people who had family suffering from such a thing. Any profits would probably make the inventor(s) delighted.
